Benefits of technology

The patent describes systems and methods for detecting and mitigating interference in wireless networks. By monitoring the rate at which packets are unsuccessfully received and the number of retransmission attempts, interference caused by beamformed signals can be detected. Once interference is detected, the system can identify the source of the interference and mitigate it by, for example, terminating transmission of the beamformed signal to a neighboring cell. The technical effect of this patent is improved service to wireless devices by effectively detecting and mitigating interference.

Problems solved by technology

However, such techniques may interfere with other communication between the access node and wireless devices.

Embodiment Construction

[0017]Systems and methods are described for detecting interference at an access node. For example, a wireless device in communication with an access node my experience interference. In an embodiment, a rate at which packets are unsuccessfully received at the wireless device and a retransmission metric (e.g., number of retransmission attempts for a packet that is eventually successfully received at the wireless device) may indicate a type of interference. For example, based on the rate and the retransmission metric for the wireless device, it may be detected that the wireless device is experiencing grating lobe interference caused by a beamformed signal transmitted from a neighboring cell (e.g., a neighboring cell at the access node).

[0018]Once such detection is performed, systems and methods may be leveraged to mitigate the experienced interference. In some embodiments, a wireless device may be identified as a source of the grating lobe interference because a beamformed signal trans...

Abstract

Systems and methods are described for detecting interference at an access node. A rate at which packets are unsuccessful received at a wireless device may be monitored, wherein the wireless device is in communication with a cell of an access node. The access node may retransmit one or more unsuccessfully received packets to the wireless device. A retransmission metric for retransmission attempts to the wireless device from the access node may be monitored. And it may be determined that communication between the cell of the access node and the wireless device is experiencing interference from a neighboring cell when the monitored rate and monitored retransmission metric meet the interference criteria.

Description

TECHNICAL BACKGROUND[0001]Telecommunication systems, such as cellular networks or other wireless networks, provide wireless services to a plurality of wireless devices in a variety of conditions. For example, an access node may serve a group of wireless devices that experience strong signal conditions while other wireless devices experience poor signal conditions. In some cases, a system may leverage various techniques, such as beamforming, to better serve wireless devices with poor signal conditions. However, such techniques may interfere with other communication between the access node and wireless devices. Accordingly, a system that effectively detects interference caused by such techniques and, in some cases, effectively mitigates the interference can provide enhanced service to users of the system.OVERVIEW[0002]Systems and methods are described for detecting interference at an access node. A rate at which packets are unsuccessful received at a wireless device may be monitored, ...
